NOTE: We have listed the Abaci sizes based on their own conversions, which shows on the tag and which we note below. HOWEVER, please be aware that if you are choosing based on your U.S. size, we would recommend getting one to two sizes down since the Abaci's conversions seem to be off. For example, if you normally wear a size 6, we would recommend getting a size 2. Please contact us for measurements on specific items.
